UMLR — Stereotyped Constraints in UML

Open Closed All
  • Key: UMLR-187

  • Summary:

    In the UML 2.2 spec (ptc/2008-05-05), there is no way to show that a constraint on a class has a stereotype or stereotype tags. I would like to see something with nested braces. For example, { <<stereotype>> constraint1: body

    {tag1=value, tag2=value}

    }.

    I recommend changing the notation from this:

    A Constraint is shown as a text string in braces ({}) according to the following BNF:

    <constraint> ::= '

    {' [ <name> ':' ] <Boolean-expression> '}

    '

    to this:

    A Constraint is shown as a text string in braces ({}) according to the following BNF:

    <constraint> ::= '{' [ <stereotypes> ] [ <name> ':' ] <Boolean-expression> [ '

    {' <valuestring> '}

    ' ] '}'

    The <stereotypes> and <valuestring> use the presentation options described in 18.3.8 (Stereotype).
